Repeater Operation; Checking The Repeater Input Signal - Icom IC-7851 Instruction Manual

■ Repeater operation

A repeater amplifies received signals and retransmits
them on a different frequency. When using a repeater,
the transmit frequency is shifted from the receive fre-
quency by an offset amount. A repeater can be ac-
cessed using split frequency operation with the shift
frequency set to the repeater's frequency offset.
To access a repeater that requires a repeater tone,
set the repeater tone frequency in the Tone frequen-
cy screen. (p. 5-38)

set the Repeater tone frequency
t
Operate in the normal way.
While using the Split function, transmission is made
on the Sub band, and the reception is made on the
Main band.
D Checking the repeater input signal
You can check whether another station's transmit sig-
nal can be received directly or not, by listening to the
repeater input frequency.
➥
While receiving, hold down [XFC] to listen on the
repeater input frequency.
